Jonathan S Lyndhurst , NJ September 09, 2014 Appliance: Kenmore Electric Range 79096112408 Kenmore Range 79096112408: Bad oven control board. How to replace Oven Control Board. Sears sent a guy out, he tested our stove and determined it to be a bad board. He told us they could fix it for 300 or we could try and find it online. All signs pointed to this being an easy fix so I ordered the part, it arrived next day (lightning fast shipping!) and in 5 minutes I had the old board out and the new one in. Probably one of the easiest repairs I have ever done. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
